Abstract

A driving control system for driving pixel driving circuits in a display apparatus includes a selecting module, a compensating circuit, and a controller. The pixel driving circuit sequentially operates during a detecting time period and a displaying period. Each pixel driving circuit comprises a driving transistor and an OLED. During the detecting time period, the selecting circuit selects at least one of the pixel driving circuits, the driving transistor in the selected at least one of the pixel driving circuits becomes saturated, the compensating circuit detects a detecting current of the selected pixel driving circuit and converts the detecting current into a specified parameter, the controller adjusts a driving voltage provided to the selected pixel driving circuit based on the specified parameter.
